Fine (fine.dev) is a software development platform aimed at startup founders, indie builders, and developers who want to build and ship web applications faster. It combines an AI coding agent with a managed full-stack hosting environment, so users can go from idea to deployed product without setting up servers or CI/CD infrastructure manually. The core AI agent works by deeply analyzing an existing codebase, generating specifications for the intended changes, and then writing code, creating branches, committing changes, and opening pull requests for human review. This makes it act more like an AI teammate embedded in a real Git workflow than a simple code-completion tool. Fine's managed backend includes serverless functions, built-in authentication, a database, and file storage, all handled automatically. Users do not need to configure or manage any of this infrastructure. The platform targets people who want to ship production-ready web apps in days rather than months. As of 2025, Fine reported roughly 20,000 users and was in public beta. It adopted Anthropic's Claude 3.7 Sonnet as its underlying model, citing its hybrid LLM and reasoning capabilities for improved reliability on complex planning tasks. A free tier was available with limited daily usage (approximately 7 messages per day on Claude 3.7 Sonnet). Fine is distinct from the similarly named 'Fin' (formerly Intercom), which was acquired by Salesforce in June 2026 for $3.6 billion and is a customer service AI platform. Fine.dev is a separate Israeli-founded company focused on software development automation and remained independently operating as of mid-2026. Key features: - AI coding agent that analyzes codebases, generates specs, writes code, and opens pull requests - Automated Git workflow: branching, committing, and PR creation without manual steps - Built-in serverless backend with authentication, database, and file storage - Cloud-based development environments for running and testing code - Full hosting and deployment included, no external infrastructure required - Customizable coding standards and feedback alignment for teams - Free tier available (limited daily messages) with paid plans for higher usage - Supports Claude 3.7 Sonnet as the underlying model for complex reasoning tasks
